The whole of the fore part of this Spider is of a rusty yellow-brown colour, the falces, maxillae, labium, and sternum being rather the darkest-the falces and labium indeed being of a darkish red-brown, the abdomen being pale dull yellow. The cephalothorax is of ordinary form, but rather small and short m proportion to the length of the abdomen, and it is sparingly dotted with fine hairs ; the normal furrows and indentations are slightly marked, but are of a deeper hue than the rest of the surface. The height of the clypeus is less than half that of the facial space. The eyes are in the usual position; they are in two equally curved transverse rows, the ends of which converge on each side but do not meet; the four central ones form a trapezoid, whose transverse is less than its longitudinal diameter; those of the hind central pair are oval, oblique, and separated by an interval about equal to the longest diameter of one of them ; the interval between each of these and the hind lateral on its side is greater than that between the two centrals ; those of the foremost row appeared to be equally separated from each other. The legs are short, moderately strong, furnished with hairs and a few black spines, these last almost all on the two last pairs; each tarsus ends with two curved, toothed claws, beneath which is a scopula which extends backwards underneath the joint; their relative length is 4, 1, 2, 3. The falces are neither very long nor strong, but they project a little forwards and are of ordinary form The maxilla, labium, and sternum present no deviation from the normal characters of the genus. The abdomen is of an elongate oblong-oval form, very sparingly clothed with hairs, and of a uniform dull yellowish colour. Spiracular plates yellow and not very large. Genital aperture small, but, as usual, of characteristic form (vide Plate LII. fig. 23). The spinners are moderate in length and strength ; those of the inferior pair are the longest and strongest. A single example of the adult female of this species was contained in the collection of Spiders kindly made for m e in Bombay by Major Julian Hobson, Staff Corps. DRASSUS DENOTATUS, sp. n. (Plate LII. fig. 24.) Adult female, length 3\ lines. The general form and structure of this Spider are of the ordinary character; but the markings on the abdomen are distinct and characteristic, as also is the form of the genital aperture. The cephalothorax is pale yellow-brown thinly clothed with hairs ; the caput is a little more convex than usual, and it is divided behind from the thorax by two fine blackish converging lines, divided at the point of convergence by another longitudinal central one. The height of the clypeus is less than half that of the facial space, being about equal to the diameter of one of the fore central eyes. |
